Swany Posted September 8, 2006 Posted September 8, 2006 I hear mixing some chloral hydrate with your first drink will keep you from becoming hungover. Does anyone here play hockey of the ice variety?
itwasntme Posted September 8, 2006 Posted September 8, 2006 If a coffee grinder didn't work, you have a shitty grinder. Try grinding for longer time. I think it was a mr. coffee brand for $20. I returned it. The thing got to 210F(laser thermometer) for about 2 minutes.
Draco_Aster Posted September 8, 2006 Posted September 8, 2006 I, personally, wouldn't bother. I have a 5Kg bag of that stuff and its a bitch to get fine. Sure it can be used in certain comps if ground down enough but I could never get it to match the blackpowder made on flour. even ballmilling it takes hours and it cakes to the mill. Just walk along the gutter an work up some money to get a new bag. Think about it....would you accept being paid $2/hr for tiresome frustrating manual labour???
rocket Posted September 8, 2006 Posted September 8, 2006 I have the same stuff and it doesn’t bother me, it gets ground up in the end and works fine. Before I put it in the ball mill with BP I just through it in the coffee grinder with a bit of charcoal so it doesn't stick to every thing.
d4j0n Posted September 8, 2006 Posted September 8, 2006 Lots of sparkly compositions call for granular aluminum. What exactly IS granular aluminum? What mesh and shape is it? Anywhere to get it besides skylighter and firefox?
Mumbles Posted September 8, 2006 Posted September 8, 2006 Granular is a particle shape. The only granular I have is -50+150. I think it goes to -325 though.
d4j0n Posted September 8, 2006 Posted September 8, 2006 I'll keep that granular aluminum in mind for next summer. So while browsing firefox's tooling I couldn't help but to notice that the formula for the magnum rocket was clearly visible (not the whistle, the first one). http://www.firefox-fx.com/images/dscn2019.jpg Is the composition safe to ram? I'm guessing that nozzle is 1/8" or 5/32".
Mumbles Posted September 8, 2006 Posted September 8, 2006 6:1:1 is a pretty standard formula. Yes, it would be safe to ram. That also sounds about right for the nozzle.
d4j0n Posted September 8, 2006 Posted September 8, 2006 Really? I've never heard of a 6:1:1 comp based on potassium perchlorate. Do ya think it need milling? edit: hah, nevermind forget the post. The covered word is probably nitrate.
weknowpyro Posted September 8, 2006 Posted September 8, 2006 Today i disected a commerical french rocket i brought for about 25 cents on my holiday. What i found inside was the usal stars,break and motor but when i had a better at the stars they were very odd indead they are like al streamers but these were like sticks about the size of those refillable pencils lead. I mean i have heard of pumped,rolled and cut but never rolled into a tiny stick.Very odd indeed but they still gave a cool effect.
TheSidewinder Posted September 8, 2006 Posted September 8, 2006 6:1:1 is a pretty standard formula. Yes, it would be safe to ram. That also sounds about right for the nozzle. Ummm....re-read that page, Mumbles. That's a 2-part fuel. 6:1:1 and then 7:3 and the instructions (as near as I can make out) say to shake ALL those ingredients in a bag. I wouldn't ram perc and benzoate even if it was mixed with BP as it looks to be. Or did I read it all wrong?? M
Mumbles Posted September 8, 2006 Posted September 8, 2006 Without reading the whole thing I'm not sure. I thought about that, but if so, why are there two different fuel mixtures? I took it as either whistle or the 6:1:1 fuel could be used, similar to the SBR tooling.
TheSidewinder Posted September 8, 2006 Posted September 8, 2006 Yeah, without the complete sheet to read we're only guessing. Re-reading it, I now think you're right about it being one or the other, and not both. Still, I would NOT the ram whistle mix though. Press it, and carefully at that. Use a good Lexan blast shield. The straight BP is ok to ram, but a shield is still a good idea.... M
d4j0n Posted September 9, 2006 Posted September 9, 2006 No I know what the whistle was, but I was curious about the first comp. I assume they call for hardwood charcoal as that is what Firefox sells themselves, and if no ball milling is involved and it's good enough for a small end burner, that comp is a real time saver.
h0lx Posted September 9, 2006 Posted September 9, 2006 weknowpyro, maybe it's flying fish fuse or something?
weknowpyro Posted September 9, 2006 Posted September 9, 2006 Ummm It could have been it, but it felt alot to heavy to be fuse. It was basically like mini sparklers so maybe it is a cheap chinese way of making stars for small rockets.
h0lx Posted September 9, 2006 Posted September 9, 2006 Historical day for me as I made and going to launch my first shell today. I's some flitter stars found on Gamekeeper and it's a 35mm canister. Didn't go for symmetry in construction.
Bug_X Posted September 9, 2006 Posted September 9, 2006 When you make paper tubes with PVA glue and wather (60/40) What makes the stronges tube? To let them dry with no fans. Let them dry with fans. Let them dry in a oven in 100C in 6 hour. Thanks / Bug
h0lx Posted September 9, 2006 Posted September 9, 2006 Just launched my shell:) anyway fans are OK, so s no fans, don't dry at 100, rether 60 or so, or the evaping water will make bubbles between layers.
shadopyro Posted September 9, 2006 Posted September 9, 2006 What is wather? i usually just use woodglue which gives very good results.
_DB_ Posted September 10, 2006 Posted September 10, 2006 My guess is that he meant to type "water". In other news I officially hate cold sores. I got my first one ever this week and it just doesn't want to go away. I bought a tiny tube of Abreva for $15.00 which doesn't seem to have any effect on it. *sigh*.......
Can you say amateur? Posted September 11, 2006 Posted September 11, 2006 Abreva was always overpriced and never worked well... Im not exactly sure how to start out here... Seeing how strict it seems, I dont want to end up being banned like an Idiot, so anyone have some advice as a relatively safe (If preformed correctly) Composition to begin with?
Rogue Chemist Posted September 11, 2006 Posted September 11, 2006 Capsaicin takes care of cold sores nicely for me. A squeeze of habenero juice on the sore burns, but the next day it was gone. The mint extract stuff for seasoning food has also worked, but I believe that to be because of all the alcohol in it.
Swany Posted September 11, 2006 Posted September 11, 2006 Im not exactly sure how to start out here... Glad you decided to play it safe. I trust you know some basics, and since you have a nice disposition chances are you will get along with everyone here quite nicely. If I were you, I would decide if I were serious about the whole pyrotechnics thing. Some people are trying to seriously limit the chemicans avalible under the pretext of keeping us safe, and therefor it may be nessisary to get some stuff fairly fast. Take a leap rather than testing the waters, if you will. Though, I may be over-reacting. I would get some basic oxidisers and fuels, keep reading lots, get some people on instant messengers to talk to, and have fun! It's an amazing hobby, I think. Go ahead and PM me if your wondering about things. Welcome to the forums.
Mumbles Posted September 11, 2006 Posted September 11, 2006 I can tell the difference between an idiot and a beginner. Don't worry about that. I'm much more forgiving for beginners than for just dumbasses. It's not nearly as strict as some other forums. I'd say probably the best thing to start with is Blackpowder. It is absolutly essential for pyro. You can start with fountains and rockets and such. They are fairly safe and pretty easy. Smoke devices arn't a bad thing to try either.
